Application filed June 30, 1894.

To all whom it may concern: v

Beit known that we, ADAM W. SEVERANOE, GEORGE J AMISON, and G ORGE W.BRAUCHT, citizens of the United States, residing at Genesee, in thecounty of Latah and State of Idaho, have invented certain new and usefulImprovements in Self-feeders for Thrashing-Machines; and we dodeclarethe following to be a full, clear, and exact description of .theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention has relation to improvements in selffeeders for thrashingmachines, and the novelty will be fully understood from the followingdescription and claim when with the annexed drawings, in Which- Figure1, is a longitudinal section of our improved device showing the sameapplied to a part of a thrashing machine. Fig. 2, is a vertical,cross-sectional view taken in the plane indicated by the dotted line 00,:r, on Fig. 1. Fig. 3, is a similar view taken in the plane on thedotted line y, y, of same figure. Fig. '4, is a side elevation of theforward .portion of the spout or frame carrying the endless feedband,and Fig. 5, is a detail elevation of the trough or bundle frame showingthe feed band tightener.

Referring byletter to said drawings :A, in-

dicates' the cylinder cap; B, a part of a cylin der, and O, the concaveof an ordinary thrashing machine, such parts being here shown simply forthe purpose of illustrating our improvements in connection therewith.

D,indicatesahorizontalframe. This frame is provided on opposite sideswith angular,

metallic barsE, which are of a form, sub-- stantially as shown, and havesecured to them boxes I), which are designed to receive a horizontallydisposed shaft F. This shaft is provided'with suitable numberof cranks0, there being two shown in the present illustration, and on one end ofthis crank shaft is fixed a wheel 01, for apurpose which will presentlyappear, andaon the other end of said shaft is fixed another wheel e, toreceive a Serial No. 516,231- (No model.)

the cranks of the shaft F, are journaled, so

that said forks will be given a vertically rotatable motion during therotary motion of the crank shaft.

Rising from the rear of the frame D, on opposite sides are posts oruprights H, which are suitably secured to said frame and are connectedat their upper ends by ahorizontal cross bar I. On this cross bar arearranged brackets or lug journals g, and in these lugs are pivoted oneend of arms J, the opposite ends of which are pivotally connected to theupper ends of the forks as shown at h, and the connecting arms areprovided at one end with a plurality of holes 2', and the upper ends ofthe forks, are similarly provided with holes It, so that the connectionbetween the forks and the cross bar I, may be lengthened or shortenedand the'throw or sweeping movements of the forks consequently regulated.This frame D,is,provided with side boards K, which may beof asuitableheight. The anguv lar irons or braces E, are extended at their rear endsbeyond the frame D, as shown, and are formed with recesses, as shown atn, for a purpose which will presently appear.

M, indicates the trough. This trough may be mainly of the ordinaryconstruction, having the vertically disposed side boards 0, therotatable shaft N, journaled transversely in bearings W, and thecylinder P, journaled 85 transversely in the opposite end to receive theendless feed beltQ. These bearings W, are secured to levers X, so as tomo've'therewith. The levers X, are pivoted at their lower'ends'to thetrough M, as shown, and. 0 racks V, are fixed to the upper portion ofsaid trough so as to be adj ustably engaged by said levers. I By thismeans it will be seen that the feed belt can be tightened as desired bysimply manipulating these hand levers. 5

The shaft or cylinder P, which is journaledt in the forward end of thetrough M, has its bearing in metallic hanger arms R, which arms aresecured to the side boards 0, as better shown in Fig. 3, of thedrawings, and their lower ends extend laterally as shown at S, and aswell as receiving through them the a journal ends of the shaft orcylinder P, they also serve as a bearing for the forward end of saidframe when placed in the projected branches n, of the angular braces orirons E, thereby makinga hinged connection between the two parts andadapting the trough M, to be quickly disconnected and connected with theframe D.

T, indicates a center board which is of a less width or height than theside boards 0. This center board is designed to divide the trough M, intwo longitudinal parts or sections and is arranged centrally therein.This board has secured to its forward end an arm 1), which risestherefrom and is secured at its upper end to the rod 10, and itsopposite end has secured to it an arm g, which depends as shown at r,and passing around the shaft N, is secured to a cross bar 8, of thetrough M. By the employment of this center board it ,will be seen thatthe bundles will be prevented from getting cross-wise as they are beingcarried up the inclined trough so as to bring the bands properly belowthe cutting knives. Rising from opposite sides of the trough M, areposts U, and on one of these posts we provide a rack or toothed bar V.

W,indicates two uprights arranged one on each side of the trough M, andin advance of the uprights U.

Journaled in suitable bearings in the trough M, between the uprights U,and W, is atransversely disposed rock shaft u. This rock shaft haseither fixed to or formed on one end, an angular branch t, connected atits free end with one of the uprights W, and fixed to the opposite endof said rock shaft is a hand lever e, which is connected at one end withthe other movable upright \V, and is designed to engage the teeth of thebar or rack V, so as to hold the said lever at a suitable point in itsrange of movement. As the uprights W, are allowed to be moved by thehand lever 11, it will be seen that by the employment of the rack, thesaid uprights may be raised or lowered as desired and locked in saidposition.

Journaled in the upper ends of the movable uprights VV, is a transverserod '10, and on this shaft are loosely arranged sleeves Z, which havedepending integral branches a.

Jonrnaled in the upper ends of the fixed uprights U, is a rotatablecrank shaft 1), and on one end of this crank shaft is a band wheel orpulley c, which is designed to be connected by means of an endless band01', with a band wheel or pulley e, on one end of the shaft P, so as toreceive motion from the latter shaft and impart the same to the crankshaft 1). Motion is given to the shaft when loose grain is used, thecutters may be removed and spreader fingers which may comprise pins orthe like, substituted. The bars are journaled at their forward ends inthe branches or arms a, of the sleeves Z, on the rod W, which is on aless altitude than the crank shaft 11, and the upper or opposite ends ofsaid bars are journaled in the cranks h, of the shaft 1). By thisconstruction it will be seen that as motion is communicated to therotatable crank shaft 12, the bars journaledthereon, whichassumeavertical oblique position, will be givcnavertically-reciprocatory movement, and as the cranks of said rod aredisposed in opposite directions, some of the bars will be movingforwardly, while others are moving rearwardly, thereby more effectivelycutting the bands, or spreading the grain as the case may be. As thegrain is thrown into the trough and carried up by the endless band, itwill be brought beneath the cutters or spreader-s and as the loose grainenters the frame D, it will be taken by the reciprocatory forks, and fedinto the cylinder of the thrasher.

Having described our invention, what we claim is The herein describedgrain feeder for thrashing machines consisting of the frame D, providedwith the metallic bars E, having their rear ends extended beyond theframe D, and provided with seats or recesses n, the crank shaft F,journaled in bearings supported by the irons E, and carrying wheels 01,e, at its opposite ends, the forks G, mounted on the cranks c, of saidshaft, the arms J adjustably connected at one end with the forks andconnected at their opposite ends with the frame D, the trough M, havingthe metallic hanger arms R, arranged in the recesses or seats n, of therearwardly extended portions of the irons E, the transverse shaft P,journaled in the arms R, at the forward end of the trough M, thetransverse shaft N, journaled in movable bearings W, at the rear end ofthe trough, the endless carrier passing around the shafts N, P, racks V,fixed on opposite sides of the trough, levers X, connected to thebearings W, of the shaft N, and adapted to engage the racks V, the fixeduprights U, and the movable uprights W", arranged on opposite sides ofthe trough M, the crank shaft 1), journaled in the fixed uprights U, therod 20, arranged in the movable uprights W, and carrying a series ofloose sleeves Z, having depending arms, the reciprocatory bars A,mounted at one end on the cranks of the shaft 1), and connected at theiropposite ends to the arms of the sleeves Z;
